As with most things: it depends.
How much risk have you taken out of your business? What is the market size and upside potential? What is employee #1's contribution expected to be? Is employee #1 your chief technologist, your CMO, or something different?
Have you closed angel or A-round funding, or are you paying them out of your pocket?
I am an East Coast startup person. Employee #1 at a post angel pre-A startup out here wants at least 1-2% with some hedging against dilution when the VCs enter.
Equity at the startups I've worked for is 4-year vesting with a 1-year cliff and monthly vesting at month 13. Most savvy negotiators will want a nut of options that vest immediately on acceptance.
If your product is not complete and you can't show that the market is itching to buy your product, a revenue-share-only package will be impossible to value.
But then again, same with the options.
